Quiz: Gravity: The Universal Force Explained

Question 1

If the distance between two objects is doubled, by what factor does the gravitational force between them change?

Accepted Answer

Quartered

Answer

Halved

Answer

Doubled

Answer

Quadrupled

Question 2

Which of the following scenarios would result in the strongest gravitational force between two objects?

Accepted Answer

Increasing the mass of both objects and decreasing the distance

Answer

Increasing the mass of one object while keeping the distance constant

Answer

Decreasing the distance between the objects while keeping their masses constant

Answer

Decreasing the mass of both objects and increasing the distance

Question 3

Why does an object in free fall accelerate towards the Earth?

Accepted Answer

Because it is pulled by the Earth's gravitational force

Answer

Because it has initial velocity

Answer

Because of air resistance

Answer

Because of its inertia

Question 4

How does the gravitational force acting on an object change as it moves away from the Earth's surface?

Accepted Answer

It decreases

Answer

It increases

Answer

It remains constant

Answer

It first increases then decreases

Question 5

If the mass of the Earth were doubled, with all else remaining constant, what would happen to the gravitational acceleration (g) on its surface?

Accepted Answer

It would double

Answer

It would quadruple

Answer

It would remain the same

Answer

It would be halved

Question 6

Which statement best describes the relationship between gravitational force and orbital motion?

Accepted Answer

Gravitational force provides the necessary centripetal force for orbital motion

Answer

Gravitational force opposes orbital motion, slowing the object down

Answer

Gravitational force is irrelevant to orbital motion

Answer

Gravitational force only affects objects in a straight path

Question 7

What would happen to the orbit of a satellite if the Earth's mass suddenly increased?

Accepted Answer

The satellite would spiral inward and collide with Earth

Answer

The satellite would move to a higher orbit

Answer

The satellite would continue in the same orbit

Answer

The satellite would be flung into space
